US Steps Up Covert War Effort in Yemen

As the unrest in Yemen continues, several different parties are vying to fill a potential power vacuum in the country, including the US. Over the past month, Washington has expanded the number of air and drone attacks in Yemen in an attempt to prevent Al-Qaeda-affiliated militants from establishing a foothold in the country. Meanwhile, American and Saudi spies are reportedly ramping up intelligence collection efforts inside Yemen. Both countries have a strategic interest in preventing Yemen from becoming a failed state.
